Collision Avoidance System for Aircraft Ground Operations
First Claim
Patent Images
1. A ground collision avoidance system (GCAS) for an object, the system comprising:
- a radio frequency (RF) sensor for sensing a location of an obstacle with respect to the object moving along the ground; and
a processor that, in operation;
determines an expected location of the obstacle with respect to the object from the sensed location and a trajectory of the object; and
generates an alarm signal when the expected location of the obstacle with respect to the object is less than a selected criterion.

Abstract
A ground collision avoidance system (GCAS) for an aircraft is disclosed. A radio frequency (RF) sensor senses a location of an obstacle with respect to the aircraft moving along the ground. An expected location of the obstacle with respect to the aircraft is determined from the sensed location and a trajectory of the aircraft. An alarm signal is generated when the expected location of the obstacle is less than a selected criterion.

9. A method of preventing a collision of an object, the system comprising:
-
sensing, using a radio frequency (RF) sensor, a location of an obstacle with respect to the object moving along the ground; determining an expected location of the obstacle with respect to the object from the sensed location and a trajectory of the aircraft, and generating an alarm signal when the expected location of the obstacle with respect to the object is less than a selected criterion. - View Dependent Claims (10, 11, 12, 13, 14, 15)
